Background: The second stage of labor involves strong maternal effort, commonly manifested as Valsalva maneuvers, which may significantly impact maternal cardiac function. Understanding these effects is essential for optimizing maternal safety during vaginal delivery.
Objective: To investigate the correlation between strong Valsalva maneuvers and maternal cardiac function during the second stage of labor in parturient women.
Methods: A correlational study was conducted on 200 parturient women in Ambon and Ternate from January 2022 to November 2024. Maternal cardiac function parameters, including heart rate, blood pressure, and cardiac output, were measured before, during, and after active pushing. Data were analyzed using appropriate correlation tests and presented in two tables summarizing maternal cardiac responses.
Results: The study demonstrated significant correlations between the intensity of Valsalva maneuvers and changes in maternal cardiac function (p < 0.01). Strong pushing efforts were associated with transient increases in heart rate, systolic and diastolic blood pressure, and cardiac output, followed by post-effort normalization.
Conclusion: Strong Valsalva maneuvers during the second stage of labor significantly affect maternal cardiac function. Clinical monitoring of maternal hemodynamics during labor is recommended to prevent potential complications.
